Duncan JM Ant II's are not noise cancelling (middle pos)
My Seymour Duncan Jazzmaster Antiquity II pickups are not noise cancelling in the middle position. According to the website, they are RWRP and should cancel noise when used both in parallel. They were marked as neck and bridge versions.
I bought them last year at the Thomann store. Is there perhaps old stock floating around that is not noise cancelling (and how old are we talking about here)?
Another possible reason is that I did a series mod at the same time. Does this setup temper with the noise cancelling in parallel mode? I know little about electronics but this should be the diagram used:

Re: Duncan JM Ant II's are not noise cancelling (middle pos)
I just got a pair and put them on my CP JM and all the wiring is stock. Middle position is NOT hum canceling either.
Called SD and they said they are not supposed to cancel. When I told the guy thats what it says on your website... he said maybe some do and some don't.
Weird huh?

Something's gotta be flipped around.

Re: Duncan JM Ant II's are not noise cancelling (middle pos)
QC issues?
There was a chap a couple of months ago who'd installed a set of Duncans that were actually out of phase when wired up 'correctly':

I'd be following up a return/replacement with the vendor.

^ Also a shame their phone support is so useless.The Antiquity II Jam for Jazzmaster neck pickup is wound RWRP so that, when used together with the bridge model, they will be hum-canceling.

Re: Duncan JM Ant II's are not noise cancelling (middle pos)
I've got Antiquity II's in my JMJM, wired with dual volumes, G&L-style PTB tone stack and series parallel switch per this article: https://reverb.com/ca/news/upgrading-ja ... iring-mods.
Definitely hum-cancelling in the middle position when in parallel as well as when in series. Maybe the leads on a pickup need to be swapped?

Swap the leads on one pickup to switch the effective wind direction. If that doesn't work, use a compass to verify that the polarity is different on the neck and bridge pickups.

Re: Duncan JM Ant II's are not noise cancelling (middle pos)
I've got Antiquity IIs in my JM and they are definitely hum cancelling in the middle position. I don't recall doing anything special other than just putting the wires where the old ones were.

Re: Duncan JM Ant II's are not noise cancelling (middle pos)
I've had two sets in different guitars and both have been hum cancelling in the middle position. Gavanti's suggestions seem like a good place to start. My guess would also be that the wires need to be flipped on one of the pickups.

Re: Duncan JM Ant II's are not noise cancelling (middle pos)
Sorry to be opening a can of worms... But it seems my setup did not have 60 Hz cycle hum anyway... Or perhaps that depends on the interference in the room at that moment? I tried it on another setup and it cancels out the 60 Hz cycle hum perfectly.

Glad to hear it. I have an overhead light I turn off and that makes a huge difference as well.Nick and the Noise wrote:Sorry to be opening a can of worms...

Re: Duncan JM Ant II's are not noise cancelling (middle pos)
I can verify that SD does indeed have an issue with some of these JM pickups. Just today I installed a pair of SD Ant IIs in my AV65 JM, and the "neck" pickup I got was definitely NOT RWRP. On top of that, it was wound to 8.9K, about 0.6K hotter than the "bridge" pickup I got. What I think happened was that someone there mistakenly labeled some (perhaps a batch) of bridge pickups as neck pickups. Instead of going through the hassle of returning it to whomever would claim responsibility, I turned it upside-down (RP), reversed the leads (RW) and ran them through the (now bottom) flatwork's holes back into the eyelets. I then removed excess solder to get the eyelets as flush as possible to the top flatwork. It's now the "bridge" pickup and works great.

Re: Duncan JM Ant II's are not noise cancelling (middle pos)
Just got some of these installed, and they are not hum-cancelling in the middle position. I pulled the covers and put the pickups near each other, and they repelled each other. Does that mean they are the same polarity?

Mine are noise cancelling in the middle position, and quite noisy on both single coils.

I think that's part of the charm of the Antiquities, they're all wound a little different, you're never sure exactly what you'll get.
All pain and troubles melted away like lemon drops beyond the contrails across the sky.
